Question

find the roots of 16 x square -24x -1 =0 using quadratic formila

Answer 1

Step-by-step explanation:

complete the square, and find the roots of the quadratic equation.

x2 + 16x = 0

X^2+2*X*8+8^2-8^2=0

(X+8)^2=8^2

X+8=+8...........OT..-8

X=0........OR........-16

x^2 + 16x = 0

(x^2+16x+8^2) = 8^2

(x+8)^2 = 64

x+8 = +8 or -8

x=-16 or x=0
